[feature request] Option to extract a single language code chunks from a multi-language notebook

[coatless]

Consider the following code cells in a quarto-document:

## Welcome {.unnumbered}

```{r}
my_list = list(1, 2, 3)
typeof(my_list)
```

```{python}
my_list = [1, 2, 3]
type(my_list)
```

Would it be possible to add a flag to quarto that specifies only R code chunks be written/evaluated? e.g.

## Welcome {.unnumbered}

```{r}
my_list = list(1, 2, 3)
typeof(my_list)
```

You could do it this way:

## Welcome {.unnumbered}

```{r}
my_list = list(1, 2, 3)
typeof(my_list)
```

```python
my_list = [1, 2, 3]
type(my_list)
```

The goal here would be to have a split notebook for curriculum purposes.

1. Python -> Jupyter
2. R -> RMarkdown/Quarto

Disabling the code chunk via dropping {} would leave data in-place.

Okay, got it. Not something we have now but something we could definitely consider.
